Moved several services into neutron.cmd.eventlet

- dhcp-agent
- l3-agent
- metadata-agent
- metadata-proxy
- metering-agent
- server

This allows us to remove explicit monkey_patch() call.

Also removed ability to execute neutron-server avoiding a corresponding
entry point.

Depends-On: I2d7081dbd4cb532332e3b66667bb8c71aa5a6658

Related-Bug: #1418541
